Mine was requested online at the bank on Monday, left account Tuesday, arrived in MT Gox account on Sunday at 3am. So 3 business days, 5 actual days. Note: this was a SEPA transfer in EUR, originating from the UK.
Exactly the same for me.....
SEPA Transferred euros from my UK online account to their french account on tuesday, received an email from MT Gox early hours of this morning say my US$ where now waiting.
Glad it wasn't any sooner as I might have been tempted to buy when the price was still high.
